Definitions

  • the present invention relates to a packaging for liquid or pulverulent products which is particularly suitable for food products and chemicals.
  • Metal containers and glass containers are markedly less commonly used than in the past : they are generally heavy, permitting little variation in form, and are relatively expensive. Glass containers are, moreover, breakable, which is a major disadvantage. As for metal containers, these are easily deformed irreversibly if they are dropped.
  • containers made from plastic material For reasons of economy, it is desirable for containers made from plastic material to be as light as possible.
  • packaging in plastic material has gradually evolved towards forms which are better adapted to the characteristics of the material, these forms making it possible to optimize resistance to vertical compression, the limit being given by a non-visible and non-permanent deformation of the packaging.
  • Plasticized cardboard boxes of the brick type for milk make it possible to save space during transportation and storage. They comprise a small quantity of plastic material and, after use, occupy a small volume in refuse provided that care is taken to flatten them.
  • These boxes are manufactured from a cardboard sheet. At least one layer of polyethylene and, optionally, a layer of another material such as aluminium are made integral with the cardboard sheet by being stuck together or by other means. This results in a particularly troublesome drawback from the ecological stand-point : the materials which form the single composite layer of the packaging cannot be dissociated from one another and thus cannot be separated by simple means. Thus, they can neither be destroyed selectively by incineration nor be recovered for the purposes of recycling. Also, since the actual cardboard has been plasticized, it is rendered rot proof.
  • the method of opening boxes of the brick type for milk is as follows : the user must lift a part, which is folded on the top of the box and folded over the sides, and cut off its corner. If the cutting operation is not performed correctly, which often occurs, milk is spilt when the user picks up the brick in order to pour out its contents. No provision is made, after opening, for the possibility of reclosing this type of packaging.
  • packaging formed from a combination of cardboard and sheets of plastic materials which can, in certain cases, be reclosed each time the product is used, has recently been developed.
  • packaging of the brick type for milk described above, whose method of opening is different, has been marketed : a pouring spout, consisting of an injection-moulded component made from polyethylene, is glued to the center of the upper wall of the box.
  • a pouring spout consisting of an injection-moulded component made from polyethylene
  • the consumer When using the container for the first time, the consumer must himself pierce a hole in the wall of the packaging, through the spout, thus creating lips which face the inside of the box and which prevent total emptying of the box.
  • the spout is applied to the outer part of the composite film forming the wall of the packaging, it can become detached in the event of impact or rough treatment.
  • any recycling of plastic material or of cardboard is impossible.
  • packaging which consists of a cardboard sheet which has been given the form of a box, in which a sheet of plastic material welded into the form of a bag is glued at several points.
  • the upper wall of this packaging is manufactured with an off-center hole.
  • a spout which is integral with the cardboard and with the sheet of plastic material is positioned at the location of the hole provided on the top of the box. Opening, closing and pouring of the product are relatively easy. Nevertheless, it is observed that, in practice, due in particular to the parallelepipedal form of the box, it is also virtually impossible to empty.
  • the packaging mentioned above is not designed in order to be filled via the spout. It must be manufactured and filled by complicated and expensive machines which make the cardboard, apply the plastic material thereto and proceed immediately to filling. In each case, this means that the manufacturer of the packaged product must transport his merchandise in bulk to the premises where the packaging is manufactured or invest in machines for manufacturing and filling the packaging, which involves additional cost.
  • U.S. Pat. No. 4,143,718 describes a packaging comprising a container surrounded by a cardboard box.
  • the design of the carton is such that it is impossible to carry out filling of the completely assembled container on a conventional filling line. It is necessary either to previously fill the inner container (which, in this case, has itself to be relatively rigid, such as a glass bottle), or to break down the folding of the carton into two partial folding operations, which complicates the apparatus of the chain. Once packing is finished, the spout is in fact accessible only by tearing part of the carton.
  • Application GB 2,228,725 describes a packaging composed of a container in plastic material surrounded by a carton.
  • the orifice of the container is arranged set back relative to the upper face of the carton so as not to extend beyond the latter.
  • the orifice of such a container clearly intended to contain corrosive liquids, is connected, for draining, to a pumping device. In this case, there is no pouring problem.
  • the invention aims to provide packaging for liquid or pulverulent products, composed of cardboard and an amount of plastic material which is small compared with the content of the packaging, which permits total separation of its constituent materials, which can be sorted before being discarded, and which permits selective collection and recycling of the constituent materials.
  • An object of the invention is to provide a packaging for liquid or pulverulent products which occupies as small a volume as possible after the product has been used.
  • a major object of the invention is to provide packaging which, although composed of two elements, has a total weight which is no greater than that of a traditional bottle.
  • the invention also aims to provide packaging for liquid or pulverulent products which can easily be stacked and palletized and which has a configuration such that the ratio of the volume occupied by the spatial requirement of the packaging to the volume of the packed product is very close to the value 1, and for this to be so while retaining the characteristics of good resistance to vertical compression exhibited by conventional bottles made from plastic materials.
  • a further object of the invention is to provide packaging for a liquid product, composed of cardboard and of plastic material, which can be manufactured on traditional machines and filled on traditional filling lines used for filling bottles.
  • the invention further aims to provide packaging for liquid or pulverulent products which makes it possible to easily pour the product contained therein, while preventing any spilling of the latter, which packaging can be opened and reclosed easily after use and which, above all, makes it possible to use all the product, so as to avoid any wastage and any mixing of product residue with other domestic or industrial refuse.
  • a further object is to reduce the handling operations required of the user.
  • a final object of the invention is to provide packaging for liquid or pulverulent products in which the risk of leakage is reduced.
  • the subject of the invention is packaging for liquid or pulverulent products, which consists in an assembly comprising a cardboard box and a bottle made from plastic material contained in this box without being attached thereto, that is to say without being glued or welded thereto, such that the bottle can be separated from the box very easily and without any tearing after this box has been opened.
  • the box in question comprises lateral walls and a transverse wall. An opening is provided in the latter.
  • the bottle comprises a base, a body, a neck capable of being engaged in the opening of the transverse wall and a spout on which a stopper is fitted.
  • the bottle occupies a position in which its neck is engaged in the opening of the transverse wall of the box and its spout is located outside the box. In this position it can be filled via the spout, the stopper can be positioned or removed as often as required and the contents of the bottle can be poured out via the spout.
  • the packaging according to the invention comprises, moreover, an element for protecting the spout, carried by the box, arranged so that it surrounds the spout and so that its upper edge extends beyond that of the positioned stopper, this element for protecting the spout comprising an enclosure formed by extensions of the lateral walls and folded-over faces adjoining these extensions, one of the extensions comprising cutter lines arranged so as to form, after detachment of the cardboard piece located between the cutter lines, a notch facilitating pouring-out of the contents of the bottle.
  • the cardboard box according to the invention is preferably formed from a single cardboard blank.
  • the extensions of the lateral walls as well as the transverse wall are formed by virtue of a double folding of the cardboard blank, the first fold forming the upper edge of the extensions of the lateral walls and the second fold forming the junction between the transverse walls and the extensions of the lateral walls.
  • the element for protecting the spout comprises, moreover, a cup capable of being engaged on the inner perimeter of the transverse wall of the box.
  • the cup advantageously comprises vertical faces which are frictionally engaged against the lateral walls of the protecting enclosure.
  • one of the extensions (which cannot be that comprising the cutter lines) comprises a window capable of forming a handle.
  • This window is delimited by cutting lines and a folding line forming a hinge.
  • the cardboard piece located between the cutting lines and the hinge can be folded over so as to leave an opening of a size such that four fingers may be inserted therein.
  • the extension comprising the window is preferably located opposite that which comprises the cutter lines, this being in the case where the box comprises an even number of lateral walls.
  • the neck of the bottle is equipped, at least over a part of its height, with means which can interact with the transverse wall of the box in order to ensure holding of the spout outside this box when the neck is engaged in the transverse wall.
  • These means may consist of a collar which surmounts the lower part of the neck.
  • the cardboard box may optionally be devoid of a base (on the side opposite the transverse wall in which an opening is provided).
  • this box can normally be provided with such a base on which the base of the bottle may bear.
  • This base may optionally be incomplete and formed, for example, from lips of the lateral walls folded inwards at the lower part of the box, the width of these edges being such that there is still an opening in the center of this box base.
  • the body of the bottle is sufficiently flexible for it to substantially match the lateral walls of the box.
  • the spout of the bottle is threaded and the stopper is threaded in a corresponding manner.
  • this type of closure of the spout is not critical in any way and many other stoppering systems may be used such as, for example, "bayonet" closure systems.
  • the neck of the bottle is equipped, in its lower part, with means which interact with the transverse wall in order to lock the neck (and thus the entire bottle) in terms of rotation when the said neck is engaged in the opening of the transverse wall.
  • the lower part of the neck and the edges of the opening may be notched. They may also have a form which is not circular, for example an oval, ellipitical or polygonal form. Successful use will be made of hexagonal, octagonal, square or even triangular forms.
  • the opening provided in the transverse wall of the box has dimensions such that the edge of this opening laterally surrounds the neck and thus holds the bottle in position.
  • the body of the bottle of the packaging according to the present invention is preferably equipped, over at least a part of its height and at least a part of its periphery, with stiffening means, for example grooves and ribs which can be arranged either in the axial direction or in the radial direction, or in a combination of the two.
  • stiffening means for example grooves and ribs which can be arranged either in the axial direction or in the radial direction, or in a combination of the two.
  • the bottle can have a substantially circular form or, alternatively, a rectangular form with rounded corners or any other desired form.
  • the box it may be cylindrical or prismatic.
  • a particularly advantageous material for manufacturing the bottle is polyethylene, but it is also possible to use polyethylene terephthalate (PET), polypropylene or other plastic materials which can be recycled or incinerated without releasing harmful gases.
  • PET polyethylene terephthalate
  • polypropylene polypropylene
  • the use of polyethylene is advantageous for more than one reason, since it is particularly suitable for recycling.
  • the packaging comprises a cup
  • the base of this cup is flush with the upper end of the enclosure.
  • the bottle of the packaging of the invention will not generally be self-supporting.
  • the packaging of the invention is no heavier than a traditional bottle of equal capacity and makes it possible to use up to three times less plastic material.
  • the external presentation of the packaging of the invention is provided by the cardboard box, for manufacturing the light-weight bottle it is possible to use waste plastic material originating from the manufacturing process for conventional packagings. It is thus possible to manufacture a single-layer bottle entirely from recovered plastic material. Its light weight, its consistency and its functionality will be identical to those of a bottle manufactured from fresh material. Only its appearance will be modified, for example if the recovered plastic material originates from silk-screen printing waste, which involves a modification of the color of the bottle.
  • the coextrusion technique today makes it possible to produce multi-layer bottles, with the aim of recycling the plastic material contaminated by the products and originating from the consumer's dustbin. For this recycling to take place, it is essential for the material which has been contaminated, and no longer offers the guarantees of cleanliness currently required for all packaging, to be separated from the contents by a layer of fresh plastic material intended to prevent contact between the recycled and contaminated material and the contents of the packaging.
  • the color of the recycled material tending towards a wide variety of grays, requires traditional bottles also to have an external layer of plastic material, referred to as the presentation layer, when the color required for the bottle is incompatible with gray.
  • a third layer of material, sandwiched between the first two layers, will permit the incorporation of waste originating from the manufacture of the actual packaging (waste which can represent 50% of the net weight of a bottle with a handle, for example) and the use of genuinely recycled material, that is to say contaminated and originating from refuse ("post-consumer" recycling).
  • the invention makes it possible to increase the proportion of recycled material by doing away with the presentation layer, which is rendered useless given that it is the cardboard which gives the packaging its attractive appearance.
  • the bottle is protected from the light by the cardboard box until the product has been used. It thus makes it possible to use plastic materials which degrade very rapidly through the action of light, that is to say UV radiation. Degradation of the plastic material commences as soon as the bottle is exposed to the light, that is to say as soon as it is separated from the box either due to human action or due to the natural decomposition of the cardboard.

  • the box 2 comprises a base 4, four lateral walls 5, a transverse wall 6 and an enclosure 7.
  • a circular opening 8 is provided in the transverse wall 6.
  • the enclosure 7 consists of extensions 9, 10, 11 of the lateral walls 5 above the level of the transverse wall 6.

  • the upper edge of the enclosure 7 extends beyond the upper edge of the stopper 16. This gives the enclosure 7, when the package is stored, a role of protecting the spout 15.
  • the extension 9 of one of the lateral walls 5 comprises a window 17 of elongated form.
  • This window 17 is delimited by a straight folding line forming a hinge 18 and cutting lines 19.

  • These cutter lines 21, 22 enable the user to detach a cardboard piece 23 of trapezoidal form. This removal renders pouring out (and, in particular, measuring) of the product contained in the bottle possible and even extremely convenient.
  • the body 13 of the bottle 3 is approximately 0.2 mm thick. As may be seen in FIG. 4, when the bottle 3 is empty, it can easily be separated from the box 2, to which it is not attached either by gluing or by welding or in any other manner. It may then be rolled by hand like a toothpaste tube, which enables it to occupy a very small volume in waste.

  • the bottle 3 occupies, relative to the box 2, a position in which its contents can be poured out (when the cardboard piece 23 has been detached) and in which it can be stored and transported without the risk of deformation of the spout. It may then be treated as a simple bottle and, particularly, be filled on conventional bottle-filling lines.
  • the neck 14 is divided into three distinct elements along its height : the lower part 24, the collar 25 and the upper part 26.
  • the collar 25 bears on the transverse wall 6 and holds the bottle 3 so that the lower part 24 of the neck 14 is permanently engaged in the opening 8 of the transverse wall 6.

It is also possible to give the opening 8 and the neck 14 an oval form.
  • the opening 8 of the transverse wall 6 has a diameter such that it encloses the lower part 24 of the neck 14.
  • FIG. 3 shows that the bottle 3 substantially matches the lateral walls 5 of the box 2. Over its entire periphery, its body 13 has a corrugated form, thus forming a succession of grooves 27 and ribs 28 disposed in the axial (vertical) direction. It is also possible to provide smooth zones corresponding to the central part of each lateral wall.
